A Novel Unit Cell Antenna for Highly Integrated Phased Arrays in the SHF Band
… to phased array implementations across the SHF band (3-30 GHz).</p> <p>This work discusses the advantages of phased arrays over continuous apertures (e.g. reflectors), reviews phased array theory, and proposes an improved unit cell design. The proposed design is 35% smaller than a dime and …

Zebrafish Cardiac Development Requires a Conserved Secondary Heart Field
… in mouse and chick. The secondary heart field (SHF) is a conserved developmental domain in avian and mammalian embryos that contributes myocardium and smooth muscle to the cardiac arterial pole. This field is part of the overall heart field, and its myocardial component has been fate mapped from …
